【问题描述】：

我有一个启动 kong 和 konga 服务的 docker-compose 文件。 Kong 正常启动，但 konga 失败并出现以下错误：

debug: Preparing database...
Using postgres DB Adapter.
Failed to connect to DB { error: password authentication failed for user "kong"

在我的 docker-compose 中，Kong 服务来自他们的 github 页面并且运行良好。我相信，问题出在 Konga 上。 Konga服务如下：

version: '2.1' 

volumes:
  kong_data: {}

services:
  db:
    image: postgres:latest
    environment:
      POSTGRES_DB: ${KONG_PG_DATABASE:-kong}
      POSTGRES_PASSWORD: ${KONG_PG_PASSWORD:-kong}
      POSTGRES_USER: ${KONG_PG_USER:-kong}
    healthcheck:
      test: ["CMD", "pg_isready", "-U", "${KONG_PG_USER:-kong}"]
      interval: 30s
      timeout: 30s
      retries: 3
    restart: on-failure
    stdin_open: true
    tty: true
    networks:
      - kong_net
    volumes:
      - kong_data:/var/lib/postgresql/data

   konga-prepare:
     image: pantsel/konga:latest
     command: “-c prepare -a postgres -u postgresql://kong@db:5432/konga_db”
     networks:
       - kong_net
     restart: on-failure
     links:
       - db
     depends_on:
       - db

   konga:
     image: pantsel/konga:latest
     restart: always
     networks:
         - kong_net
     environment:
       DB_ADAPTER: postgres
       DB_HOST: db
       DB_PORT: 5432
       DB_USER: konga
       DB_PASSWORD: 
       TOKEN_SECRET: km1GUr4RkcQD7DewhJPNXrCuZwcKmqjb
       DB_DATABASE: konga_db
       NODE_ENV: production
     depends_on:
       - db
     ports:
       - "1337:1337"

如何解决身份验证错误？

【解决方案1】：

我遇到了同样的问题，我通过在konga-prepare 命令中添加密码解决了这个问题：

docker run --rm --network=kong-net pantsel/konga:latest -c prepare -a postgres -u postgresql://kong:kong@kong-database:5432/konga_database
